Scientists from the University of Graz (Austria) published the results of a study of "intermittent fasting". This is a special type of diet in which meals are separated by large time intervals. The size of the interval is two days, of which one full day a person does not eat anything, and the next day, for 12 hours, he can eat as he wants. Plus two 8-hour sleep sessions for a total of 36 hours without food versus 12 hours with a meal.
A study by an Austrian team showed the benefits of fasting. Participants in the experiment, as expected, tried to compensate for the long period of hunger during the allowed meal period - but could not eat much more than usual. As a result, although overeating did take place, there was no complete compensation for the calories burned, the difference reached 35%. And in 4 weeks of the experiment, people lost up to 3.5 kg of weight.
The huge advantage of such a diet is its simplicity. You do not need to count calories, the weight of meals, you do not need to think about what and when to eat. Just one full day a person spends without food, getting along with several glasses of water, and then pleases himself with delicious. Psychologically, this is perceived much easier than waiting for a long period of hardship and costs inherent in conventional diets.
The flip side of the coin is that scientists do not yet have sufficient data on the effect of such fasting on the body with prolonged practice. And although experiments with the participation of volunteers for 6 months did not give negative results, experiments with rodents showed a higher percentage of morbidity among the "starving". Probably, the problem is in immunity - if the body lacks energy, it is more difficult for it to fight diseases, and it is not difficult to pick up an occasional minor infection.
